Watts Radiant’s RadiantPERT is a new line of polyethylene-raised temperature tubing for use in hydronic heating, cooling, snow melting and distribution applications. The RadiantPERT tubing includes ratings up to 180° F (82° C) at 80 psi and offers greater flexibility than other tubing products. RadiantPERT tubing is constructed with five layers. The core and outermost layer are PE-RT. Sandwiched in the middle is an integral ethylene vinyl alcohol DIN Standard 02 barrier that limits oxygen diffusion through the walls of the tubing.
